“…On the other hand, as a typical zeolite imidazole skeleton material, ZIF-8 possesses a large-enough surface and plentiful active sites, as well as owns inverse electric charges against PMs, which favors trapping PMs by electrostatic interaction. Meanwhile, there are plenty of functional groups on the ZIF-8 surface, offering extra attraction for adsorption of PMs. − In virtue of the synergistic effect of the porous structure of the fiber membranes and the electrostatic interaction of ZIF-8, the ZIF-8@CCM-loaded composite nanofiber membrane exhibits superior PM removal performances (Figure S5) as compared with the reported literature.…”

Ambient particulate matter (PM) is one of the major pollutants in the atmosphere. Due to its small size, PM2.5 can penetrate the bronchial tubes and lungs, posing a serious threat to public health. Thus, methods allowing for the facile fabrication of efficient filtration materials are highly desirable. In this paper, we report a double-pore composite nanofiber membrane toward highly efficient and antibacterial filters. Specially, zeolite imidazole framework-8 nanoparticles coated with curcumin (ZIF-8@CCM) were prepared and spun with a polymer solution through a Y-channel via a microfluidic spinning strategy, generating a double-pore structure in the composite nanofiber. In virtue of the high porosity and permeability of the polymer nanofiber, as well as the large-enough surface and the abundant active sites of ZIF-8, the composite nanofiber membrane exhibits excellent PM removal performances. Outstanding filtration efficiencies of 99.41, 99.97, and 100% were achieved for PM0.5, PM2.5, and PM10, respectively. In addition, due to the antibacterial properties of ZIF-8 and CCM, the composite nanofiber membrane shows superior antibacterial properties. This work provides a facile pathway to fabricate a ZIF-8@CCM-loaded composite nanofiber membrane via microfluidic spinning, which will stimulate the design and development of versatile and high-performance filters.

Antibacterial materials that prevent bacterial infections and mitigate bacterial virulence have attracted great scientific interest. In recent decades, bactericidal polymers have been presented as promising candidates to combat bacterial pathogens. However, the preparation of such materials has proven to be extremely challenging. Herein, photoactive silk fibroin/polyvinyl alcohol blended nanofibrous membranes grafted with 3,3’,4,4’-benzophenone tetracarboxylic dianhydride (G-SF/PVA BNM) were fabricated by an electrospinning technique. The premise of this work is that the G-SF/PVA BNM can store photoactive activity under light irradiation and release reactive oxygen species for killing bacteria under dark conditions. The results showed that the resultant G-SF/PVA BNM exhibited the integrated properties of an ultrathin fiber diameter (298 nm), good mechanical properties, robust photoactive activity and photo-store capacity, and great photoinduced antibacterial activity against E. coli and S. aureus (99.999% bacterial reduction with 120 min). The successful construction of blended nanofibrous membranes gives a new possibility to the design of highly efficient antibacterial materials for public health protection.

“…It is highly urgent to develop alternative antimicrobial strategies and approaches to tackling this serious issue. Recently, both organic- and inorganic-based materials have been increasingly used to combat the crisis, such as molybdenum disulfide for releasing near-infrared light-induced nitric oxide and cobalt-doped nickel oxide nanoparticles for enhancing the catalytic effects of reactive oxygen species on bacterial biofilms [ [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] ]. It is noteworthy that bismuth as a relatively environmental-friendly heavy metal has been used for catalysis, energy storage and biomedicines [ [12] , [13] , [14] , [15] ].…”
